수소화 연소합성법을 이용한 Mg-xNi 금속수소화물의 수소저장특성에 관한 연구 = Hydriding Behavior of an Mg-xNi Alloys Prepared in Hydriding Combustion Synthesis

다국어 초록 (Multilingual Abstract)

Hydriding combustion synthesis (HCS) can produce full hydrides of alloys and in a short time. The conventional process based on ingot metallurgy cannot produce Mg-based alloy easily with the desired composition and the cast product needs a ling activation process for the practical use of hydrogen storage. In this study, the hydridin g properties of Mg-xNi (x=5, 13.5,54.7wt.%) alloys prepared by hydriding combustion synthesis were evaluated. The hydrogen storage capacity and kinetics of HCS Mg-xNi alloys were strongly dependent on the content of Ni. The HCS Mg-13.5wt.%Ni alloy shows the hydriding behavior to reach the maximum capacity within 30 min. and the reversible H2 storage of 5.3wt.% at 623 K.
